BUG #6727: Column does not exist exception has no error code
The following bug has been logged on the website:
Bug reference: 6727
Logged by: Patrick Tucker
Email address: tuckerpmt@gmail.com
PostgreSQL version: 9.1.1
Operating system: Windows
Description:
The SQLException that is thrown when performing a query that has a column
name that is not valid, does not exist, does not contain an error code. We
are forced to do a string comparison to figure out if a particular exception
is caused by an invalid column name. This is not ideal. A fix would be
greatly appreciated.
Thanks,
Pat

Could you provide a specific example? When I try this I see an error
code, 42703:
regression=# \set VERBOSITY verbose
regression=# select nosuchcol from int8_tbl;
ERROR: 42703: column "nosuchcol" does not exist
LINE 1: select nosuchcol from int8_tbl;
^
LOCATION: transformColumnRef, parse_expr.c:766
There may indeed be someplace where the errcode was forgotten, but
without a concrete example it's hard to find where.

Interesting, the test case that I ran was performing a simple SQL statement
like the following: select "a" from table
I wonder if the version of the driver I am using needs to be updated or
even the database?
Thanks,
Pat

Thanks again,

Thanks again,
A self-contained test case - a small Java program that connects to a
test DB, runs a query, and reports the result vs what you expected the
result to be - would be helpful.
